Operate the engine until the oil temperature stabilizes.
The temperature must be between 82°C [180°F] and
93°C [200°F].
Observe the oil rifle pressure as the oil temperature rises.
Observe the oil pressure at the oil main rifle. The pressure
must be as follows:
Oil pressure at idle (minimum allowable) 70 kPa [10 psi]
at 93°C [200°F].
At no load governed speed: 240 to 310 kPa [35 to 45 psi].
If the pressure is within these specifications, the lubri-
cating system is operating properly.
